so you can host fine on your pc, but you're wanting to host on your mac, and its giving the error?
the wiiu that i bought came with 5.2, and i updated to 5.4 thinking it would be as easy to run exploits on as 5.3.2 is. the exploits for 5.4 use a .mp4 bug instead of the html files that are used in 5.3.2. it took me forever to find info pertaining to anything 5.4 loading. but anyway i uploaded the homebrew launcher that i am using, i also included loadiinegx2 and ftpiiu. i also included the files for loading it on 5.4, and mongoose "for windows, but downloading the mac version should work too".
unzip the file to a location of your choice, copy the wiiu folder to your sd, go into the www folder and run mongoose. mongoose will load a web browser on your pc showing the index file in the www folder. in your address bar take the ip and type it into the web browser on your wiiu. "example:
http://192.168.1.3:8080 is mine". dont go to the page yet. after you type the ip into your wiiu's browser, add "/payload.mp4" without quotes. "example:
http://192.168.1.3:8080/payload.mp4 is mine". go to that and itll load the kernel exploit and reload the browser. go to the address again and itll load homebrew launcher.
for some reason the index refused to work properly for me, so i loaded the mp4 directly. if the kernel exploit fails it will kick you out and bring you into internet settings. back out all the way to the home menu and try again. self host works for me 99% of the time, while net hosted exploits never work for me. hope this helps, and sorry for the wall of text.
